Carbon Steel Pipe Reducer

USD39 USD38

Concentric Reducer 10" x 8" STD SMLS BE ASTM A420 WPL6

General Details

Carbon steel pipe reducer is one type of buttweld fittings in material grades ASTM A234 WPB, A860 WPHY 65 and A420 WPL6 for low temperature service. The other butt weld fittings also can be delivered in a short time, such as elbow, tee, cross and cap. What is the difference? Pipe reducer has one connection method that BW only. Not like them, also have socket weld and threaded types.

Types of Carbon Steel Pipe Reducer

Carbon Steel Concentric Reducer

Carbon Steel Concentric Reducer

Concentric Reducer

The concentric reducer is made with both inlet and outlet on a common center line. Compare with eccentric type, it is less costly to manufacture adaptable to most piping installations.

Carbon Steel Eccentric Reducer

Carbon Steel Eccentric Reducer

Eccentric Reducer

The eccentric reducer has the reducing outlet end off center. In contrast with concentric reducer, that can be hung or suspended flush against a flat ceiling or wall.

What is Buttweld Pipe Reducer?

Steel pipe reducer is used in piping system to change the diameter of pipe. ANSI / ASME B16.9 Butt weld pipe reducer is an pipe connector or pipe joint that reduces the size of pipe from larger diameter to smaller. The reduction in size is mainly equal to the average smaller and larger pipe diameter. It comes in two types that Concentric Reducer and Eccentric Reducer. The Concentric Pipe Reducer is used in vertical piping system. The Eccentric Pipe Reducer is used in horizontal piping system.
